This makes me wonder, what gear would I use if were to shoot at that level of photojournalism, in the kinds of conditions they face?
I'd want to shoot something robust and lightweight, with current image quality. Lenses should be as light as possible. I'd still use at least one micro four thirds camera, like the Panasonic G9 II or Olympus OM-1. For a full frame camera, I'd be tempted by a Sony A9 or A7R IV, as this would offer maximal image quality, and there are a good number of relatively small, fast E mount lenses. Mind you, I've never shot with a Sony mirrorless camera, I might not like it, haha.
What about you fine folk? What gear would you shoot if you were a Magnum level photographer?
